DOUBLE PACKAGING AND CUSHIONING STRIP Filed Dec. 31, 1952 INVENTOR IAN ALAIRD ATTORNEYS United States Patent DOUBLE PACKAGING AND CUSHIONINGSTRIP Ian A. Laird, Glasgow, Scotland, assignor to Valiant Products,Inc., Milwaukee, Wis., a corporation Application December 31, 1952,Serial No. 328,947

2 Claims. (Cl. 206-62) This invention appertains to a packaging andcushioning strip for the edge of a glass plate or pane of the type shownin the Martin Van Antwerpen Patent No. 2,603,349, issued July 15, 1952.

One of the primary objects of the present invention is to provide acushioning strip which can be partially pre-forrned by a paper converterand shipped in a flat condition, and thereafter folded and set up forapplication to the glass at its point of use.

Another salient object of the invention is to provide novel means forconstructing a packaging and cushioning strip for the edges of glassplates or panes, so that the same can be set up for use without theemployance of adhesives or fastening clips, etc.

A further object of this invention is the provision of a packaging andcushioning member formed from a single strip of material, embodying twoor more V-shaped members having cushioning tongues struck out therefrom,with means for utilizing certain of the tongues as interlocking elementsfor holding the cushioning and packaging member in its assembled form,the construction being such that the interlocking tongues also performthe function of cushioning the glass.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described and claimed and illustrated inthe accompanying drawing, in which drawing,

Figure 1 is a longitudinal sectional view through the improved packagingand cushioning strip in its set up condition, the section being taken onthe line 11 of Figure 2, looking in the direction of the arrows;

Figure 2 is a plan view of the cushioning strip in its set up conditionwith parts thereof broken away and in section to illustrate structuraldetail;

Figure 3 is a transverse sectional view through the strip taken on theline 3-3 of Figure 2 looking in the direction of the arrows, and

Figure 4 is a plan view of the strip in its flat form for shipping to aconsumer, and prior to being folded for use.

Referring to the drawing in detail, wherein similar reference charactersdesignate corresponding parts throughout the several views, the letter Sgenerally indicates the improved packaging and cushioning strip for oneor more plates of glass G, shown in broken lines in Figure 1.

The strip S is formed from a single length of corrugated or like board,of a certain desired length and width, as best shown in Figure 4. Thismaterial is weakened along intermediate parallel lines 5 on oppositesides of the transverse center thereof and by parallel weakening lines6, adjacent to the opposite ends thereof. Between the weakened lines 5and 6 the strip is slotted by spaced parallel slits 7. The materialbetween the slots 7 is slotted transversely, as at 8, at a pointintermediate the ends of the parallel slots 7 to provide tongues 9 and10. The strip is also weakened by score or like lines 11 on its underface. These score lines 11 extend transversely 2,750,032 Patented June12, 1956 "ice of the strip and are arranged between the lines 5 and 6.This is also shown in Figure 4. The strip beyond the weakened lines 6and adjacent to its opposite ends is provided with cutout tongues 12 andthe striking out of these tongues 12 forms keeper openings 13 for thetongues 10 when the strip is set up for use, as will later appear.

The strip shown in Figure 4 is shipped to a consumer in its fiat formand when the strip is to be used on the glass, the same is folded by theuser in the following way.

The portions of the strip S beyond the weakened lines, now indicated bythe reference character 14, are folded back on the lines 6 and V-shapedportions 15 are made by bending in the tongues 9 and 10 and folding thematerial or strip on the lines 11 and 5. The folded back portions 14 nowprovide an outer ply and the V-shaped portions 15 in effect, form aninner ply. The tongues 12 are bent outwardly to provide the keeperopenings 13 and the tongues 10 are inserted in these keeper openings.The tongues 12 bear against the tongues 10 and provide a frictiontension on the tongues 10. This holds the strip in its set up conditionand the same can be applied to the glass plates by placing the strip onthe edge of the plates with the plates in the slots in the V-portions15, the slots being defined by the bending of the tongues 9 and 10. Thetongues 9 and 10 and also the tongues 12 form a cushion for the edge ofthe glass plates. Lateral shifting of the plates in the V-portions 15 isprevented due to the engagement of the walls of the slots formed in theV-portions with the sides of the glass plates.

Obviously, with the two V-portions, the strip can be bent intermediatethe V-portions around a corner.

From the foregoing description, it can be seen that I have provided anefficient and simple means for forming a cushioning and packaging strip.These strips can be placed around the glass at the desired points andthe glass with the strips can he slipped into a shipping container (notshown).

Changes in details may be made without departing from the spirit or thescope of this invention, but what I claim as new is:

l. A packaging and cushioning member adapted to be placed about the edgeof a sheet of glass comprising a longitudinally extending integral striphaving inwardly projecting substantially V-shaped portions and foldedback end cushion portions, said V-shaped portions being arranged inlongitudinal alignment and being provided with longitudinally extendingnotches, said notches being also in longitudinal alignment for receivingthe glass to be protected, the bent back end portions being providedwith keeper openings, cushioning tongues struck out from the slots inthe V-shaped portions, and certain of said tongues being received in thekeeper openings, and tongues struck out from the keeper openingsengaging the tongues inserted in said keeper openings.

2. A packaging and cushioning member comprising a longitudinallyextending integral strip having an inwardly projecting substantiallyV-shaped portion and folded back end cushioned portions, each includinga base having a keeper opening and cushioning tongues struck out fromthe sides of the V-shaped portion forming a slotted V- shaped portion,one of said cushioning tongues being received in one of said keeperopenings.
